Virgil implies that the fallen individuals have succumbed to ignorance or moral failure, leading to a loss of wisdom and rationality. By stating they have lost the "good of the intellect," he suggests that true knowledge and understanding are essential for a virtuous life. This loss signifies a separation from higher moral and intellectual pursuits, resulting in a diminished existence. Ultimately, it reflects the idea that the intellect is vital for achieving virtue and fulfillment.
